How the Tool Works & Odds Explained
Simply enter a value in any of the fields above, and all other fields will automatically be
converted in real-time. This tool helps you understand the relationship between different odds
formats and their implied probability.
- Decimal Odds
-
The most common format in Europe, Australia, and Canada. The value represents the total
payout for every 1 unit staked (stake + profit). For example, a €10 bet at 2.50 odds returns
€25.
Profit calculation: Profit = (Stake × Decimal Odds) − Stake
Quick way to interpret: Decimal odds show how much you get back in total
for each 1 unit staked. Higher odds mean higher potential profit, but lower probability.
- Fractional Odds
-
Popular in the UK and Ireland. They show the potential profit relative to the stake. For
example, 3/2 means you win 3 units for every 2 units you bet.
Profit calculation: Profit = (Stake × Numerator ÷ Denominator). So a €10
bet at 3/2 returns €15 profit (plus your €10 stake = €25 total).
Quick way to interpret: The fraction shows how much you win compared to
what you bet.
- American (Moneyline) Odds
-
Used primarily in the USA.
Positive odds (+): Shows how much you win on a 100-unit stake. For example,
+150 means you win 150 units if you bet 100 (total payout = 250 units).
Negative odds (−): Shows how much you must stake to win 100 units. For
example, −120 means you must bet 120 units to win 100 (total payout = 220 units).
Quick way to interpret: Positive numbers = underdog, higher profit negative
numbers = favorite, smaller profit.
- Hong Kong Odds
-
Similar to Decimal odds, but they represent only the profit, not the total payout.
Profit calculation: Profit = Stake × Hong Kong Odds. For example, a €10 bet
at 1.50 odds returns €15 profit (total payout = €25 including the €10 stake).
Quick way to interpret: The number shows how much profit you make per 1
unit staked.
- Malay Odds
-
Can be positive or negative. Popular in Malaysia and parts of Asia.
Positive odds: Shows how much profit you make relative to your stake. For
example, +0.50 means you win 0.50 units for every 1 unit staked.
Negative odds: Shows how much you must stake to win 1 unit. For example,
−0.80 means you must bet 0.80 units to win 1 unit.
Quick way to interpret: Positive = underdog, smaller stake gives smaller
profit negative = favorite, must stake more to win 1 unit.
- Indonesian Odds
-
Similar to American odds but scaled differently. They are the default format in Indonesia.
Positive odds: Shows profit relative to 1 unit stake. For example, +1.50
means you win 1.50 units for every 1 unit staked (similar to +150 American odds).
Negative odds: Shows how much you must stake to win 1 unit. For example,
−1.20 means you must bet 1.20 units to win 1 unit (similar to −120 American odds).
Quick way to interpret: Positive = underdog, higher potential profit
negative = favorite, must stake more for 1 unit profit.
- Implied Probability (%)
-
This isn’t an odds format, but represents the percentage chance of an outcome happening, as
implied by the odds.
Calculation from Decimal odds: Implied Probability (%) = 100 ÷ Decimal
Odds.
Calculation from Fractional odds: Implied Probability (%) = Denominator ÷
(Numerator + Denominator) × 100.
Quick way to interpret: Shows how likely the bookmaker thinks an outcome
is. Higher probability = more likely, lower payout; lower probability = less likely, higher
payout.
